Mastering Ruby Blocks & Iterators

Level-up your Ruby skills and improve the design of your code
by mastering Ruby blocks and iterators in this example-driven,
hands-on video course.

Ruby 2.0

Design powerful, elegant Ruby code using blocks!

Blocks are an intrinsic and powerful aspect of the
language. Many of the methods in the Ruby standard library assume you
have a solid understanding of blocks. And blocks are used pervasively in
Ruby gems (including Rails) and all well-designed Ruby code. If you're
not using blocks then you're probably doing it wrong. This
course is your path to mastery!

“I've been using Ruby for a few years and bumped into blocks but
I was never really getting them. Your course helped me finally
wrap my head around them! Now I'm off to refactor some of my
code!”
Hans verschooten

“This course taught me a number of great techniques… Even
more valuable are the use cases, which set the
course apart from many other programs that teach the how, but
not the why.”
Randy Burgess

Learn the Pragmatic Way

Learn by example with over 40 code samples
Each in-depth example illustrates how blocks are
used effectively in a variety of real-world situations. You'll become a more
effective all-around Ruby programmer and have a deeper understanding of both
the "how" and the "why".

Block Basics
To be an effective Ruby programmer, you
need to be very proficient with blocks. We'll start with the basics
and work up to advanced block usage. In the end you'll be able to
read and write any code that uses blocks.

Custom Iterators
Ruby's built-in iterator methods—each, times, and so on—
aren't "magical" once you understand how to yield to a block. Learn how
to design your own classes and APIs using custom iterators like the
ones you use every day.

When, Why, and How to Use Blocks
Once you're comfortable with the syntax, the next level is to understand when and why to use blocks. And the best
way to do that is by looking at lots of good examples. You'll learn how to effectively apply blocks in a variety of situations to make your code more expressive, concise, and flexible.

Design Techniques & Patterns
Blocks offer a different (powerful!) style of programming that
should influence the design of your code. Throughout the course
we'll examine many use cases where blocks elegantly solve common
problems. Discover how to use blocks to remove unnecessary code,
manage resources, and more! You'll be able to immediately apply
these techniques and patterns to your own code.

Master the Enumerable Module
The methods in the Enumerable module—select, reject, map, reduce, and friends—are particularly great examples of the power of blocks. And once you graps blocks, the secret to all these methods is suddenly revealed. Master the Enumerable methods and you'll be a more efficient Ruby programmer!

Real-World, Practical Examples
No dry definitions or boring theory here. This course is
loaded with good examples of blocks and iterators used in
various scenarios. By seeing recurring patterns in different
contexts, you'll come away with a clear understanding of not just
how blocks work but, equally important, when and
where to use them.

For Beginner To Intermediate Ruby Programmers

Does using blocks feel mysterious?
In this course we walk through over 40 code examples that illustrate
how blocks work so you can use them with more confidence.

Want to design your code the Ruby way?
You'll learn design techniques, patterns, and idioms that
you can then apply to your own code.

Ready to level up?
With a deeper understanding of the when, how, and why of blocks,
you'll be well on your way to mastering Ruby.

“This course, as well as all the other Pragmatic Studio courses,
approaches perfection! The tone is pleasant, the
explanations are clear, the exercises are interesting, and the course
is ideal for practicing and learning.”
Bruno Dusausoy

“I highly recommend this for anyone, not just those who want to
learn Ruby, but also to those who want to learn
good software design in general.”
Elliot Kleiman

“I really thought I had a good grasp on Ruby blocks, but I was
mistaken. I am NOW quite confident about my understanding of
blocks, and mastery over them. I suddenly feel newly
empowered!”
Thom Parkin

“I really liked the step-by-step explanations about how blocks work
and how the internal methods are implemented. Also, super explanatory animations!”
Haris Dimitriou

“I have a much better understanding
and can confidently implement blocks using yield. Also, the Execute
Around pattern you teach is magnificent, and since finishing the class
I'm writing methods with fresh eyes!”
Dan Wagner

“I loved the real-life examples,
rather than contrived code, in this course. These examples made it easy to
relate the techniques to my own code.”
Steve Willis
